(4 pack) Nature's Miracle Cat Stain and Odor Remover Foam for Carpet, Hard Floors, Fabric and Furniture, 17.5 oz

I'm only partway done with first use, and I'm already in love. The carpet in an RV we purchased several months ago probably needed to be replaced when we bought it, but definitely needed to be replaced a few months into housing an elderly, nearly-incontinent rescue. In the meantime, I've tried everything. Starting w/ homemade vinegar %26 baking soda type tricks, moving onto traditional carpet cleaners, and eventually enzyme-based cleaners, I've spent hundreds of dollars over several months to no avail. I didn't follow instructions %26 fell asleep shortly after first use last night. Woke up to reapply as per instructions and already noticed it looks %26 smells soooo much cleaner. It's lasted a good thorough spraying (probably much more than most people would use especially for spot treatment) on approx ~60 square feet x 2. I applied the second layer today %26 used an old carpet cleaner bottle that came with bristles on top to rub it in, then immediately ran to buy another bottle. Even if I have to use another bottle or a bottle per month moving forward, it's entirely worth it. I also love the smell, but chemicals (Gain, etc) don't bother me.
